This Painless Performance "Remote Master Disconnect Switch" comes with a mechanical latching solenoid that is great for everyday use and will also act as an anti-theft device—the latching solenoid will lock the switch and the battery current will be off so no one can start your car. This switch works great for cars that are not driven too much. When you operate the latching solenoid, you are not using current to turn the solenoid on or off, therefore it won't drain your battery. The solenoid is rated at 110-amps continuous duty and is activated by a momentary push-button switch, which can be hidden under the dash. For proven electrical performance, Painless Performance is what you want.
